Question

我从这篇优秀文章中学习了如何测试图像文件上传： https://jeffkreeftmeijer.com/2010/2014/using-test-fixtures-with-carrierwave/

为我的应用调整这些想法，我已经得到了有效的测试：

test "uploads an image" do
    pic = Picture.create(:image => fixture_file_upload('/files/DJ.jpg','image/jpg'), :user => User.first) 
    assert(File.exists?(pic.reload.image.file.path))
end

我想为用户界面测试相同的东西，所以我认为这个测试也会通过：

test "create new picture" do
    capybara_login(@teacher_1)
    click_on("Upload Pictures")
    fill_in "picture_name", with: "Apple"
    attach_file('picture[image]', Rails.root + 'app/assets/images/apple.png')
    check("check_#{@user_l.id}")
    check("check_#{@admin_l.id}")
    click_on ("Create Picture")

    @new_pic = Picture.last
    assert_equal "Apple", @new_pic.name
    assert @new_pic.labels.include?(@user_l)
    assert @new_pic.labels.include?(@admin_l)
    assert @teacher_1, @new_pic.user
    assert File.exists?(@new_pic.reload.image.file.path)
end

但它在最后一行失败，断言文件的存在。

以下是我认为与我相关的test_helper部分。如果有人认为有必要，我可以展示整个test_helper。

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require "minitest/reporters"
require 'capybara/rails'
Minitest::Reporters.use!

CarrierWave.root = 'test/fixtures/files'

class CarrierWave::Mount::Mounter
  def store!
    # Not storing uploads in the tests
  end
end

class ActiveSupport::TestCase
  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  fixtures :all

  include ApplicationHelper

  include ActionDispatch::TestProcess

  CarrierWave.root = Rails.root.join('test/fixtures/files')

  def after_teardown
    super
    CarrierWave.clean_cached_files!(0)
  end
end

在开发和生产过程中，一切似乎都按预期工作。

提前感谢您的任何见解。
